I bought a 4U 400mm Dissipante case from the Diyaudio store for my SIT amp. Nice case but also not cheap.

This is what I used: https://www.ebay.com/itm/323530741005?hash=item4b53ef550d:g:xTIAAOSwOxRb3HG5 Nicely made

No, I bought a nice Chinese one (yes they do exist).

I just bought a ticket. I am looking forward to hearing the Jubes.

I can't resist, PM sent.

I(f I didn't already have an XP-4080 I would be all over this. Asking price is less than an Minidsp Flex with XLR outputs.

I have a pair of M125s and am using the Weber solid state rectifiers recommended by Bob Latino. Do you think these are a good choice, or would it be better to use tubes?

You can also link channels so that any change made to one is also applied to the other. You can pick only those parameters you want to be common.

I own the same amp with Gold Lion tubes. I use it primarily as a headphone amp. With a pair of LCD-3 phones and a good R2R dac it sounds very good.

While I have no doubt this is true at least regarding distortion measurements, I have owned very powerful amps which sounded great at low volume levels. Both a Phase Linear 400 II and a QSC PLX1804 (900WPC @ 4 Ohm) sounded good at any volume. I am using the QSC amp on Quarter Pies at less than a watt on average. Overkill never sounded so good. Neither was quite as good as my 25 WPC class A DIY Pass amp, but that is IMHO in another class.

I have my IB sub manifolds in the floor. 2 manifolds with 2 18" drivers in each. Drywall is not as good at isolating the sound from the back of the drivers. Low distortion, measured flat to 12 Hz and able to shake the house. These are not as efficient as horn subs, but watts are cheap. No large boxes in the living room, just what looks like cold air return grates for the furnace.

I have a PLX-1804 running Quarter Pies. 900 WPC amp running at less than a watt. Overkill, but it sounds good.

I have replaced the fans on 2 QSC PLX amps with quiet ones. They never get warm and sound great.

If you like the ACA, you would love some of the other Pass DIY amps. I have built an F5 and an M2x. IMHO, the M2x is an end game amp as long as 25 WPC is enough. I am using mine on the mids with BMS 4592ND drivers on K-402 horns and the sound is very good.

I used to use a MiniDSP 4x10 HD and currently use a Xilica XP-4080. I didn't notice a difference in sound quality when I switched, but prefer the Xilica's user interface. I think either is a good choice. The MiniDSP is still in production. The Xilica is discontinued and may be hard to find. I also had a MIniDSP 2x4 non HD for my subs. I would not recommend the non HD.

I like the idea of a heavy metal rod. It should lower the center of gravity and make it less likely kids or cats will knock it over.

I had a pair of 901 series IIIs and a Phase Linear 400 II amp. That amp showed me that amps do matter, even at low volume. I don't miss the speakers, but wish I still had the amp.

"AS IS", you wouldn't expect them to work for that price.

I use RP-150m speakers for computer audio and find they perform very well within their limits. I also own RP-600m's and don't think their tweeters are a big step up.

Between the BA-1 and the Schade feedback amp, I will be able to scratch my amp building itch for some time to come. Thanks for the advice!

I built the M2x, F5 and ACA. I prefer the M2x over the F5. I didn't win the Vfet lottery, so bought Tokin SITs and am building a Sissy SIT. I am hoping it combines the best traits of my SS class A amps, and my 300b SE tube amp. I have been sidetracked by my newly acquired K-402s, I have to re-arrange my living room to fit them in, then I will get back to amp building.

I agree, I am using DIY PASS design class A amps for mids and highs and can highly recommend them. I am also building a SIT amp and hope it out performs the M2x I am using for mids. If it does, I will move the M2x to HF duty and retire the ACA I am using now.

I listened to this combo at Dave A's a few weeks ago, you don't need new speakers ever.

I am using these horns with BMS 4592ND drivers. I am running active with Quarter Pies and it sounds good. I am getting K-402 horns in a few weeks and will compare.
